Not just PayPal, which I use quite a lot.
I also discovered
vodafone.122.2o7.net
microsoftwindows.112.2o7.net
microsoftsto.112.2o7.net
msnportal.112.2o7.net
in my cookies list.
Needless to say the 2o7.net domain is now blocked completely (I use OpenDNS).
Through a combination of browser, hosts file and DNS configurations, I am gradually reducing the amount of cr@p dropped onto the Dastard PCs.
